Clark-hurth CMP 40, CMP 45, CMP 50S 2000 Service Manual

If you are tearing into a CMP 40, CMP 45, or CMP 50S, you need the actual factory book. Aftermarket knockoffs skip steps, guess at clearances, and put your work on the line. Clark-hurth CMP 40, CMP 45, CMP 50S 2000 Service Manual is the exact PDF the dealer techs used. 528 pages of French and English text, full wiring diagrams, and every torque spec you can’t afford to fudge.

I’ve seen guys snap head bolts using aftermarket charts that were off by 20 ft-lbs. That wrecked a brand-new cylinder head. This manual gives you the factory numbers straight from Clark-hurth’s 2000 release. No translations, no condensation. The “Sécurité” section (Safety Maintenance) covers proper jacking, blocking, and towing procedures that keep the machine off your chest. Page 2 of the PDF shows the structure—every group and section has a unique ID so you can jump straight to what you need without flipping 500 pages.

Engine 1004-42 Diesel: Full Rebuild Procedures

The “MOTEUR 1004-42 DIESEL” chapter runs from specs to special tools list. It covers cylinder head assembly, piston and connecting rod sets, crankshaft, timing drive, block, and lubrication. Beginners often rush the timing calibration section—this manual walks you through “Calage du moteur” step by step. It also includes the tool list so you know what to buy before you start. No guessing which puller fits; the manual tells you the part number.

For the gasoline/LPG crowd, the “MOTEUR A ESSENCE/GPL (4.3L, V6)” section handles diagnostics, oil and filter change, converter stall test, and a full engine overhaul. Torque sequences for the 4.3L are in the “Révision du moteur 4.3L, V6” subsection. Don’t trust aftermarket data on a V6 that runs propane—one lean backfire can lift the intake manifold.

Transmission: Specs and Overhaul Steps

The transmission chapter covers fluid specs, filter intervals, and a full teardown. You’ll find clutch pack clearances, regulator valve adjustments, and the exact method for checking charge pressure. Every transmission repair I’ve done using an aftermarket manual has missed at least one shim or spring location. The OEM book marks those details in bold—no skimming allowed. For related drivetrain info, check the Manual Transmission overview on Wikipedia if you need background theory, but stick to this manual for hands-on work.

3 Critical Safety Sections You Must Read Before Lifting

Don’t skip “ENTRETIEN DE SECURITE”. It covers lifting, jacking, blocking, and towing. These lift trucks weigh several tons. We had a tech in San Antonio crush his foot because he blocked the frame with a single stand after the bottle jack leaked. The manual says to use two stands on the designated lift points. It also lists tow chain capacity requirements. This section is short—three subsections—but it saves you a hospital visit.

Get the Right Torque Data from the Factory

Torque values appear throughout the engine, transmission, and hydraulic sections. The manual prints them in Nm with inch-pounds where applicable. I’ve seen DIYers use the same torque for a 10mm bolt as a 12mm bolt because a generic guide said “tighten firmly.” Not here. The cylinder head bolts for the 1004-42 have a specific sequence and angle. The brake calliper bolts are listed separately. You cannot fake this data. The factory intended it for trained technicians—if you’re a beginner, follow the sequence exactly and use a calibrated wrench.

Does This Manual Cover the Brake and Steering Systems?

Yes. “CIRCUIT DE FREINAGE” includes service brakes, parking brake, and creep speed brake. The steering chapter breaks down the steering unit, priority valve, and cylinder rebuild. “Dépose et remplacement du circuit de direction” walks through removal and replacement. Hydraulic system specs and pump overhaul are in “CIRCUIT HYDRAULIQUE”. If you’re replacing a mast cylinder, check “MÂTS” for chain adjustment and cylinder repair. The 528 pages leave nothing out.

Periodic Maintenance Schedule

The “MAINTENANCE PERIODIQUE” section has service plans and a scheduled maintenance programme. It tells you when to change hydraulic oil, engine oil, transmission fluid, and filters. It also lists inspection intervals for hoses, belts, and mast chains. Stick to this schedule and those CMP trucks will run years past auction resale. Most owners ignore the mast chain lubrication interval and pay $800 for replacements.

For general manual transmission knowledge, Manual Transmission articles can supplement your understanding, but the book on the bench is what counts.

Does this manual include the 4.3L V6 engine?

Yes. The V6 gasoline/LPG engine section covers specifications, diagnostics, overhaul, and the converter stall test.

Is it in English?

The PDF is bilingual French/English. All technical procedures are in both languages.

How do I find the torque spec for the transmission valve body?

Look in the transmission overhaul section under “Contrôles et détection des pannes”. The manual uses a group-section-page ID system; the valve body torque appears in a table next to the spool valve disassembly.

Can I print this?

Yes. The PDF is fully printable. I recommend printing the safety section and keeping it near the lift point.

Don’t waste billable hours chasing data from a Chilton clone. This is the OEM file—528 pages, 2000 edition, straight from Clark-hurth. Access the Factory Manual and put it on the tablet next to your tool box.
